The following post contains an interesting video link showing how the ice cores were examined to reveal the past record of temperature. At the very least this shows that the past 10000 years have been warmer than the present – something that climate alarmists have tried to deny. Of course this does not mean that increased CO2 levels do not cause warming, but the unknown factor is how much of the current warming is cased by CO2 and how much is due to natural causes?
